LANTERN.

SPECIFICATION forming part of Letters Patent No. 248,256, dated October 11, 1881. Application filed May 2, 1881. (N model.)

To all whom it may concern Be it known that I, EDWARD P. FOLLETT, of Rochester, Monroe county, New York, have invented a certain new and useful Improvement in Lanterns; and I do hereby declare that the following is a full, clear, andexactdescription of the same, reference being had to the accompanying drawings, in which- Fignrel is an elevation, partially in section, of the lantern. Fig. 2 is an elevation, showing the hinged body turned back on the base.

Fig. 3 is a bottom view of the body of thelantern. Fig. 4 is a cross-section in line 00 as, Fig. 1. Fig. 5 is a perspective view-of the spring locking-arms.

My improvement relates to side-tube lanterns; and it consists in the construction and arrangement of parts, hereinafter more fully described.

In the drawings, A represents the oil-fount, which is of ordinary construction. It has in its top an open fiarin g socket, a, in which rests the body of the burner B. This body is slight- 1y cone-shaped, so as to press tightly into the socket and hold without a screw-thread. The burner has a circular rim, 1), which projects outward horizontally some distance, upon which rests the inner ends of the side tubes holding the burner down, as will presently be described. The top of the oil-fount has an upwardly-projecting bead, c, atits edge,which forms a seat for the cap 0, that forms the bottom of the body of the lantern. This cap forms the air-chamber proper, receiving the air from the side tubes and supplying the same to the cone D, which surmounts the air-chamber and surrounds the burner. The cone is attached to a supporting-plate, E, upon which rests the bottom of the globe G, said plate having a series of holes, (I d, in its outer edge to admit air to the globe. The cap 0 is hinged at one side to the top of the oil-fount, as shown atf, Fig. 2, so that the whole body of thelantern, including the air-chamber, cone, supporting-plate, globe, and side tubes,including the dome, can be turned off to one side, leaving the burner exposed and convenient to be lighted. On top of the fonnt is a hooked catch, g, and in the cap 0 is a springlatch, h, having an end which extends out through the cap, so as to be operated easily by hand. When the lantern is closed the latch engages with the catch and holds the parts fast together.

H H are the side tubes, which pass through the sides of the air-chamber O and project some distance in. and when the lantern is closed rest and bear on top of the circular rim 1) of the burner, thereby holding the burner firmly down in its socket. burner is always held firmly down when the lantern is closed and -in use, but the side tubes rise and separate therefrom when the lantern is Opened thereby leaving the burner free to be lighted, or to be removed for filling the lamp. The inner open ends of the side tubes are covered and screened by shields k of wire-cloth or perforated metal folded around in a half-circle, but left open at the ends to allow escape of the air. The side tubes extend but part way up and are left open at their tops. To the tops is attached a frame or arch, I, of strap metal extending over the top of the lantern.

To the frame, alittle distance above the side tubes, is attached a cap, K, consisting of aring of sheet metal having. an opening in the center, through which slides up and down the cylinder L, which clamps upon the top of the globe and holds itin place. This cylinder is attached to a dome, M, to which are secured two springarms, N N, passing through slots in the top of the frame I, and connecting at their upper ends with a spring-bail, P. The arms have notches m m, which engage with the edges of the slots, and thus hold the dome'down. By springing the arms inward they can be drawn up, together with the dome and cylinder, thereby releasing the globe.

Heretofore in this style of lantern there has been need of some means of stiii'enin g the connection of the top of the side tubes with the bottom of the arch or frame, and to supply this need curved plates r r are attached at their top to the inner side of the arch,'and at their bottom to the inner side of the side tubes, as shown in Fig. 1, spanning the top of the side tubes and leaving them open for the free admission of air. These plates stand radially and pass through slots or openings in the cap K. The plates form firm stiffeners to the top By this means the 0f the side tubes and prevent any twisting action of the same to which they are liable, also prevent strain on the arch, and,in addition to this, they serve as deflectors to turn the wind and direct it down into the side tubes.

The two spring-arms N N are made from a single piece of sheet metal, together with a base-piece, s, which has claws t n at its ends. The base-piece rests on top of the lower wall, w, of the dome, and the claws pass through holes in said wall and are clinched on the under side. The base-piece gives a firm support on the wall, and has sutiicient elasticity in its body to allow the necessary spring of the arms sidewise or toward each other.

The device is simpler, cheaper, and more ef fective than where the two arms are made separate from each other.

Rivets may he used, instead of the claws v o, to secure the parts together.

What I claim as new is- 1. In a lantern, the combination, with the fount A and hinged cap 0, of the side tubes, H H, entering the cap, and having projecting ends which extend in and rest upon the rim b of the burner B, and hold it in its socket, as described.

2. In a side-tubelantern, the combination, with the fount A, of the cap or air-chamber G, supporting-plate E,cone D, and side tubes, H H, entering the cap, all connected to form one body, the cap 0 being hinged to the founr, so

that the whole body of the lantern can be turned off to one side, leaving the burner exposed, as herein shown and described.

3. The combination, with the burner B and side tubes, H H, of the screens k 70, folded to inclose the ends of the side tubes, but open at their ends, as and for the purpose specified.

4. In a lantern, the combination, with the side tubes, H H, and arched frame I, of the plates 1' r, made ot'curved form, connecting said parts, forming stififeners to the same, as well as deflecting plates to turn the currents of airinto the side tubes, as herein shown and described.

5. In a lantern, the spring-arms N N, formed in a single piece with the plate or body 8, and standing edge to edge, the body serving as the spring, and being attached to the dome by claws or rivets,as herein shown and described.

6. I11 a lantern, the combination, with the side tubes, H H, and frame I, of the ring K, fixedly attached to the frame above the side tubes, bracing and supporting said parts, and forming a guide to the cylinder L, which passes through the ring and secures the globe, as herein shown and described.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.

EDWARD l. FOLLETT.
